ALARM REGISTER FOR METERS.

"Application filed May 4,

The object of thisinvention is to provide for meter registers which must be capable of being set backto zero after operation, an alarm which shall be sounded on the delivery of a predetermined volume of liquid as in the case. of gasoline filling stations.

The invention will be explained more fully hereinafter with reference to the accompanying drawing in which it is illustrated and in 0 which:

Figure 1 is a view i elevation, as seen fromthe right-hand in igure'2, of so much of a register with its associated devices, as is necessary to enable the application of the invention thereto to be understood.

Figure 2 is a view of the same in sectional elevation, as seen from the left-hand in Figure 1. 3

In the embodiment of the invention illustrated in the drawing, the registering mechanism, indicated generally at a, is enclosed within a suitable casing b which supports a suitable dial a. tended to be supported upon a meter of suitable construction from which the registering mechanism receives motion through a vertical shaft d. In the construction shown, the shaft d, through gears d and d drives a shaft d which carries a unit indicatorhand 80 d. The shaft (1, in the construction shown, also carries a gear 11* which meshes with a pinion e on a. drive shaft 6' which is mounted in suitable bearings in the. supporting I framework aid carries a worm e for the op- 3 eration of a totalizing register of usual con 'struction, indicated by broken lines at f.

The shaft e also carries a worm e" which drives, through suitable transmission gearing, not necessary to be shown herem, a shaft It which carries, usually through a sleeve 12?, an indicating hand or pointer h and has, in front of the protecting glass 0,a handle it by which the pointer k can be set back to zero, after'an operation, and with it the shaft h. On the shaft h is secured a cam z for cooperation with a hammer or striker k, pivoted at 7:, formed with a lip 70 which overhangs the framework for the purpose of limiting the'movement of the body of the hammer, and carrizies, on a spring arm k, a

The register casing is in- 1926.- Serial No. 106,779..

hammer head is, for cooperation with a gong its initial or zero position, through contact with the dog In", raises the hammer-7c until, in the continued operation of the registering mechanism, the high point of the cam passes beyond the dog is, whereupon the hammer falls and the head is, by reason of the spring arm k strikes the gong k and gives the audible signal required. Through the provision of the pivoted dog 70", which is free to swing in a counter-clockwise direction,

t e resetting of the indicator M, which is a ected by rotationof the shaft h and the cam 'i in a clockwise direction, as seen from the rear, in Figure 1, is permitted, the dog 70 swinging freely as it is struck by the drop of the cam.

It Will be understood that the invention is in no wise dependent upon the construction of the registering mechanism except so far as it involves the reverse rotation of the shaft It and cam z" in the operation of resetting. v

I claim as my invention:

In a meter register having a driving means, an indicator, "a shaft carryin the indicator, and means to reset the shaft by reverse rotation, a cam with a sharp drop carried by the shaft, a gong, a pivoted hammer, a dog freely movable in one direction pivoted on the hammer and operated by the cam, and a stop on the hammer to prevent movement of the dog in the opposite direction, whereby reverse rotation of the cam causes, the dog to move away from the stop while maintalning the alarm mechanism in operative condition during normal-operation of the register.

This specification signed this 29 day of April A. D. 1926.
